Material supporting pallet



Nov. 30, 1948. F. s. SULLIVAN MATERIAL SUPPORTING PALLET Filed May 9, 1946 orties MATERIAL SUIPRTING PALLET Application May 9, 1946, Serial'No. @68,412 Claims. (Cl. 248-120) This invention relates to pallets for handling work or other materials.

In a modem industrial plant the materials and` the oor to `permit the insertion of the truck or lifter arms or prongs beneath the pallet. These pallets are constructed of wood or metal and are providedwith bars or legs for support. If provided with cross beams to strengthen the supporting plate they stand at an undesirable height and are heavy and cumbersome to handle, or else the truclr can pick the pallet up only from two sides instead of four sides.

It is the object of the present invention to construct a pallet of minimum weight. of maximum strength and which stands only a small distance above the door and which can be picked up from all foursides by the truck. A further object is o pallet from which the work can be lifted by passing arms under the work resting upon the Pallet.

In the drawings:

Fig. l is a perspective showing the pallet in relation to the truck.

Fig. 2 is a plan view of the pallet.

Fig. 3 is an end View of the same.

Fig. 4 is a side view of the pallet.

The pallet is formed by two corrugated plates.

The upper plate i has the narrow corrugations l -2 and the wider corrugations 3; The latter provide a larger supporting surface. The under plate t is provided with the narrow corrugations d and the wider corrugations 6. These corrugations may be of any dimensions as may be required. These plates are superimposed one upon the other and spot welded or fastened, together at the points l. The wider corrugations 6 on the under plate provide a larger surface for supporting the pallet on the floor and hence prevent any creasing or marking of heavywork placed on the pallet. The truck t with the extended pick-up arms or prongs 9 can be inserted under the pallet at the ends, as shown in Fig. l, the prongs going into the openings of a pair of smaller corrugations, as shown in this ligure, or in the vopening between the upper plate and a downwardly opening corrugation. Or the truck arms can be inserted at the side under the upper plate, entering any of the downwardly opening corrugations.

It will also be seen with' this pallet that the lifting arms, whether they be on a truck or some other form of lifting apparatus, can be inserted over the top of the pallet along the upwardly opening corrugations for the purpose of getting under a stack of the work and removing the work from the pallet, when. this is desirable. This cannot be done on any wooden platform pallet or any other form Iof pallet with which I am familiar. This is very advantageous in handling certain classes of work. It may be desired to handle this work by some other form of lifting device than an industrial truck-some form of elevator, such as a lifting crane, hoist or sling.l

This pallet has great strength because the cor rugations, in eilect, form beams and at the same time supporting surfaces. The pallet has a plurality of cross beams by reason of the cross corrugations. At the same time the pallet can be relatively light because of great strength provided by the crossed corrugations or beams in the plates.

This palletv is much lower than the usual run of pallets, such as pallets that have legs or other supporting devices, especially the wooden type of pallet. This is Very advantageous in cases where the pallet is used to truck the work into a freight car and the pallet is shipped loaded with the work. The pallet Vwill therefore occupy less space which is advantageous in stacking the pallets for .return to the supplier for again loading with work and shipping in freight cars.

The truck or lifter may approach from any side and can 'pick up the pallet from two of the sides by inserting the truck arms under the under plate or under the bottom oi' the upper plate, and can pick the pallet up from the other two sides by inserting the truck arms in the opening between the top of the bottom plate and an upwardly opening corrugation of the upper plate'.

I claim:

l. A load supporting pallet for use with a lifter having pick-up arms, comprising a pair of cor- Y rugated plates having pickup-arms receiving open end corrugation placed one upon the other with the corrugations running crosswise and secured together, the said corrugations having flat bottoms which provide the contact surface with the noot and the supporting surface for the load.

2. A load supporting pallet for use with a lifter having pick-up arms, comprising a pair of plates with dat bottom open end corrugations of dimens ions to take pickup-arms placed one upon the other with the corrugations running crosswise and secured together at the bottom of the channels iormed by the corrugations where these channels lie together, the said flat bottoms forming the contact surface with the oor and the supporting surface for the load.

3. A load supporting pallet for use with a lifter having pick-up arms, comprising a pair of plates with at bottom open end corrugations of dimensions to take pickup-arms placed one upon the other with the corrugations running crosswise and secured together at the bottom of the channels formed by the .corrugations where these channels lie together by a metallic union, the said fiat bottoms forming the contact surface with the floor and the supporting surface for the load.

4. A load supporting pallet for use with a lifter having pick-up arms, comprising a pair of relatively heavy stii plates with iat bottom open end corrugations of dimensions to take pickuparms placed one upon the other with the corrugations running ycrosswise and secured together at the bottom of the channels formed by the corrugations where these channels lie together by spot welding, the said nat bottoms forming the contact surface with the floor and the supporting surface for the load.

plate having open ends to receive the arms 0r prongs of the lifter between the two plates from two sides and the corrugations of the under plate being open at the ends to receive the arms or prongs of the lifter from the other, two sides of the pallet.
